Dr Marcus Wilson has an ongoing collaboration with researchers at the University of Adelaide to try to describe how electrical signals form in muscles as a result of transcranial magentic stimulation.
We have constructed a numerical model that simulates how the human central nervous system responds to a short magnetic pulse applied to the brain. We have then matched this model to existing experimental data provided by The University of Adelaide and so determined strengths of key interactions in the brain, such as the strength between populations of excitatory brain cells in the cortex. We have then mapped how these strengths change following a brain stimulation intervention across many individuals.
In the future we aim to use the model to suggest brain stimulation interventions tailored to an individual, providing an improved chance of a stimulation having the desired clinical effect.
